If the mains cable is damaged, it must be replaced by a special connection
cable which is available from the manufacturer or its customer service.
Do not use the device if it is visibly damaged!
The controller is equipped with 14 relays in total to which loads such as pumps,
valves, etc. can be connected:
Relays 1 ... 13 are semiconductor relays, designed for pump speed control:
Conductor R1 … R13
Neutral conductor N (common terminal block)
Protective earth conductor ⏚ (common terminal block)
Relay 14 is a potential-free relay:
R14-A = normally open contact
R14-M = centre contact
R14-R = normally closed contact
Depending on the product version, mains cables and sensor cables are already con-
nected to the device. If that is not the case, please proceed as follows:
Attach exible cables to the housing with the enclosed strain relief and the corre-
sponding screws.
The temperature sensors (S1 to S12) have to be connected to the terminals S1
to S12 and GND (either polarity).
The cables carry low voltage and must not run together in a cable conduit with
cables carrying a voltage higher than 50 V (please pay attention to the valid local
regulations).The cable lentghs depend on the cross sectional area.
Example: up to 100 m at 1.5 mm², up to 50 m at 0.75 mm². The cables can be ex-
tended with a two-wire cable.

Different solutions for visualisation and remote parameterisation are available on
the website www.resol.com. On the website, rmware updates are also available.
Note
During remote parameterisation, the symbol will be displayed, the con-
troller will not carry out any control function.
Note
For more information about accessories, see page 96.
2.4 SD card slot
The controller is equipped with an SD card slot.
With an SD card, the following functions can be carried out:
• Store measurement and balance values onto the SD card. After
the transfer to a computer, the values can be opened and visual-
ised, e.g. in a spreadsheet.
• Prepare adjustments and parameterisations on a computer and
transfer them via the SD card.
• Store adjustments and parameterisations on the SD card and, if necessary, re-
trieve them from there.
• Download rmware updates from the Internet and install them on the controller.
Note
For more information about using an SD card, see page 89.
3 Step-by-step parameterisation
The DeltaSol® MX is a controller that offers a broad variety of functions to
the user. At the same time, the user has a lot of freedom in congurating them.
Therefore, to set up a complex system, careful planning is required.We recommend
drawing a sketch of the system rst.
If planning, hydraulic construction and electrical connection have all been carried
out successfully, proceed as follows:
1. Running the commissioning menu
After the commissioning menu has been nished (see page 19), further adjust-
ments can be made.The commissioning menu can be repeated any time by means
of a reset (see page 89). Additional adjustments will be deleted.
For further information about the commissioning menu see page page 19.
2. Registering sensors
If owmeters, ow switches, Grundfos Direct Sensors™, flow rate sensors, humidi-
ty sensors, room control units,remote controls, switches and/or external extension
modules are connected, these have to be registered in the Inputs/Modules menu.
For further information about the registration of modules and sensors see page
91.
In some functions, the Sensorcong. channel is available for sensor selection, in
which sensors not used and not registered can be selected. The selected sensor
input will automatically be set to the sensor type required for the function.
3. Activating optional functions and/or heating circuits
The basic solar system has been adjusted during commissioning. Now, optional
functions and/or heating circuits can be selected, activated and adjusted.
Outputs available can be allocated to functions which require an output. The con-
troller always suggests the numerically smallest output available.
Sensors can be allocated to more than one function.
For further information about the solar optional functions see page 50.
For further information about the optional arrangement functions see page 63.
For further information about heating circuits and optional heating functions see
page 73.

Speed control
In the Speed adjustment channel, the speed control for the output can be acti-
vated or deactivated respectively. If Ye s is selected, the channels Min., Max. and
Adapter will appear.
In the Min. adjustment channel, a relative minimum speed for a pump connected
can be allocated to the output
In the Max. adjustment channel, a relative maximum speed for a pump connected
can be allocated to the output.
If the speed control signal is generated via a VBus®/ PWM interface adapter, the
Adapter option has to be activated. If Ye s is selected, the relay will switch on or
off (no burst control). Speed information will be transmitted via the VBus®.
For functions controlling loads which are not speed controlled, the speed control
will not be shown on the display (e. g. the bypass type, mixer).
If the temperature difference reaches or exceeds the switch-on temperature differ-
ence, the pump switches on at 100 % speed for 10 s. Then, the speed is reduced to
the minimum pump speed value. If the temperature difference exceeds the adjusted
set value by 1/10 of the rise value, the pump speed increases by one step (1 %). The
response of the controller can be adapted via the parameter Rise. Each time the
difference increases by 1/10 of the adjustable rise value, the pump speed increases
by one step until the maximum pump speed of 100% is reached. If the temperature
difference decreases by 1/10 of the adjustable rise value, pump speed will be de-
creased by one step.

Relay option
If the Relay option is activated, a relay can be allocated to the output selection.
PWM/0-10 V option
If the PWM/0-10 V option is activated, a PWM/0-10 V output can be allocated to
the output selection.
In the Signal channel, a selection between a PWM or a 0-10 V signal can be made.
In the Prole channel, characteristic curves for solar and heating pumps can be
selected.

Blocking protection
In order to protect the pumps against blocking after standstill, the controller is
equipped with a blocking protection option. This option can be activated in the
output selection submenu.The Blocking protection option can be adjusted in the
Basic settings / Blocking protect. menu (see page 89).
Manual mode
In the Manual mode adjustment channel, the operating mode of the output can be
selected. The following options are available:
Off = Output is switched off (manual mode)
Min. = Output is active at minimum speed (manual mode)
Max. = Output is active at 100 % (manual mode)
Auto = Output is in automatic mode
Note
After service and maintenance work, the operating mode must be set
back to Auto. In manual mode the control logic is overridden.
4.6 Sensorconguration
Some sensors must be registered and congured in the Inputs/Modules menu
(see page 9 and
page 91 ).
In some functions, the Sensorcong. channel is available for sensor selection, in
which sensors not used and not registered can be selected. The selected sensor
input will automatically be set to the sensor type required for the function. Regis-
tering the sensor in the Inputs/Modules menu is then no longer necessary.
Note
If a sensor is used as the temperature sensor of a function, the sensor
types Switch, Fern, BAS, Impulse and none will not be available for
the corresponding input.

5 Commissioning
When the hydraulic system is  lled and ready for operation, connect the controller
to the mains.
The controller runs an initialisation phase in which the directional pad glows red.
When the controller is commissioned or when it is reset, it will run a commis-
sioning menu after the initialisation phase.The commissioning menu leads the user
through the most important adjustment channels needed for operating the system.
Commissioning menu
The commissioning menu consists of the channels described in the following. In or-
der to make an adjustment,press button ➄. Adjust the value by pressing buttons ❹
and ❷, then push button ➄ to con rm. The next channel will appear in the display.

8. Completing the commissioning menu:
After the system has been selected or the scheme
number has been entered, a security enquiry appears.
If the security enquiry is con rmed, the adjustments
will be saved.
ÎIn order to con rm the security enquiry, press
button ➄.
ÎIn order to reenter the commissioning menu
channels, press button ➆. If the security enquiry
has been con rmed, the controller will be ready
for operation.
Note
The adjustments carried out during commis-
sioning can be changed anytime in the corre-
sponding adjustment channel. Additional func-
tions and options can also be activated and
adjusted (see page 44).
Set the code to the customer code be-
fore handing over the controller to the
customer (see page 91).
5.1 Basic systems
The controller is pre-programmed for different basic systems. The selection de-
pends on the number of heat sources (collector  elds) and heat sinks (stores, pool).
The selection of the basic solar system is one of the most important adjustments
and is thus requested already in the commissioning menu.
First, the number of collector  elds and stores will have to be adjusted, then the
hydraulic variant.
Note
A solar system with store loading in layers is implemented as a 2-store
system (store top = store 1; store base = store 2).
The system selected is visualised by the corresponding number of store and col-
lector symbols. The exemplary  gure shows system 2.3.x with 2 collector  elds
and 2 stores.
The hydraulic variant refers to the different actuators that are to be controlled.
They are visualised on the display by means of symbols, when the variant is selected.
The upper symbol indicates the actuator belonging to the collector  elds, the lower
one the actuators belonging to the stores.
The exemplary  gure shows the display indicated when system 2.3.2 has been se-
lected.
In this case, each collector  eld has a 2-port valve, the stores are loaded by means
of pump logic.
The controller allocates corresponding output and sensor settings for each basic
system.The allocations of all combinations are shown in chap. 5.2.
7a. Scheme (if 6. = Scheme):
ÎEnter the scheme number of the desired system.
7b. Selection of the solar system (if 6. = Sys-
tem):
ÎAdjust the desired solar system (number of collec-
tors and stores, hydraulic variants).
